The following is Dr. Sharpe's description from a specimen in the Leyden
Museum: "General colour of the upper parts olive-brown, shading into
chestnut-brown on the rump, upper tail-coverts, and tail; the inside web of
each feather much darker, approaching black on the back; lores dark brown;
eye-stripe very obscure; lesser wing-coverts brown, darkest on the inside
web; median coverts dark brown, with large olive-brown tips; greater
coverts nearly black, broadly tipped, and narrowly margined towards the
base with olive-brown; primary coverts black, with a broad olive-brown
patch on the outer webs; tertials dark brown on the inner web, and
olive-brown on the outer web; secondaries brown, margined with olive-brown
on the outer webs; primaries brown, with the basal half of the outer webs,
and a spot where the emargination begins, olive-brown; tail-feathers
chestnut-brown; ear-coverts brown; underparts olive-brown, shading into
white on the chin, throat, and centre of belly; under tail-coverts dark
brown, with irregular diamond-shaped white tips; axillaries brown; under
wing-coverts brown. Geocichline markings on inner webs of quills dirty
white. Wing 3.8 inches, tail 2.6, culmen 0.85, tarsus 1.07, bastard primary
0.8."
The only person who ever collected this short-tailed Ground-Thrush was
Kittlitz, who obtained four specimens, one of which is in St. Petersburg,
one in Frankfurt, one in Vienna, and one in Leyden. Neither Holst, nor Alan
Owston's Japanese collectors obtained specimens, though their special
attention was called to it. Therefore, unless these recent collectors left
unvisited the most important island of the group, we must suppose that it
became extinct.
Habitat: Bonin Islands, south-east of Japan.
